I'm out of Mistic Metal Mover, I don't need a gallon, I don't need 3 containers of different versions.

Only one local place has MMM and it's the 2 vs the regular.  Mail order is usually more than one pint or shipping is the same as the price of a pint.

What is the difference between Mistic Metal Mover and Mistic Metal Mover2?

Side story, a friend gave me the first can 20 years ago and extolled the powers.   I set it aside and kind of forgot about it.  Then one day I was tapping a ¼" hole and didn't have exactly the correct drill so went a tiny bit smaller.  Half way through it got stuck.  I couldn't back it out, the tap was twisting and I was sure it was going to break.  At that point I noticed the Mistic Metal Mover in the cabinet next to the taps and thought, why not.  I squirted some on and tried backing the tap out, it backed out.  I then tried going back and tapping the hole, it worked.  Very hard but no binding.  We've used this in my shop and my neighbors shop ever since for tapping and drilling.
